ABSTRACT:
A turbine rotor disk assembly for an axial flow gas turbine engine includes a rotor disk (18) and a faceplate (22) axially engaged therewith by rotationally engaged securing means such as a pair of corresponding hooked members (42, 44). Disengagement of the faceplate (22) and the rotor disk (18) is prevented by the cooperation of an axially projecting tab (58), integral with the turbine blade, (20) and a corresponding faceplate recess (60).
